GetPrimaryDCName
by DevX Pro
I'm trying to get the PDC name for a domain on my network using the following code. It works fine within the VB IDE, but the moment I compile it and run it as an executable, it errors out with either NERR_DCNotFound(2453): Could not find domain controller for this domain or ERROR_BAD_NETPATH(53): The network path was not found Any idea what's going wrong? Here's my code: Private Declare Function NetGetDCName Lib "NETAPI32.DLL" _ (ServerName As Byte, DomainName As Byte, DCName As Long) As Long Private Declare Function lstrcpyW Lib _ "kernel32.dll" (bRet As Byte, ByVal _ lPtr As Long) As Long Private Declare Function NetApiBufferFree Lib _ "Netapi32" (ByVal pBuffer As Long) As Long Public Function GetPrimaryDCName(ByVal DName As String) As String Dim DCName As String, DCNPtr As Long Dim DNArray() As Byte, DCNArray(100) As Byte Dim result As Long DNArray = DName & vbNullChar result = NetGetDCName(0&, DNArray(0), DCNPtr) If result 0 Then Err.Raise vbObjectError + 4000, "CNetworkInfo", result Exit Function End If lstrcpyW DCNArray(0), DCNPtr result = NetApiBufferFree(DCNPtr) DCName = DCNArray() GetPrimaryDCName = Left(DCName, InStr(DCName, Chr(0)) - 1) End Function

Run EXE as Logged-On User
by DevX Pro
Let's assume I am logged onto an NT Workstation as a normal user. Using one of your 10-Minute Solutions I managed to get the LogonUser API to log me in as the Administrator (i.e., returned True) with VB. Now I want to shell an EXE as the logged on Administrator and not myself. For example, this viruscan update, which requires Admin privileges: c:\Temp\sdat4080.exe How do I do this (I believe one solution is the CreateProcessAsUser API, but I don't know how to use it)?
